Without a host, bed bugs enter a dormant, low-metabolism state (diapause), slowing their development and activity to survive for months, even up to a year or more under ideal cool, humid conditions, though they eventually die from starvation, with younger nymphs being the most vulnerable, while adults can last much longer, waiting in cracks and crevices for a host's return, signaled by heat and carbon dioxide.
At lower temperatures (50° F – 60° F), a particular instar may take two or three days longer to molt to the next life stage than a nymph living at room temperature. However, if a bed bug nymph does not have access to a host, it will stay in that current instar until it is able to find a blood meal, or it dies.
Bed bugs do not abandon a space simply because humans are absent. They prefer to remain close to resting areas where a host usually appears, and they hide in mattress seams, furniture joints, skirting boards, cracks in plaster, electrical outlets and similar refuges.
Bed bugs can go without feeding for 20 to 400 days, depending on temperature and humidity. Older stages of nymphs can survive longer without feeding than younger ones, and adults have survived without food for more than 400 days in the laboratory at low temperatures.
Without food, bed bugs can live in a wall for 20-400 days. However, the temperature and humidity level in the wall must be considered. Bed bugs will die faster in the winter season or if the environment is arid and cold. Conversely, they will live longer in summer or if the climate is moist and warm.
Quick answer: Yes — it is possible to get rid of bed bugs permanently, but only with the right professional treatment. Chemical sprays often fail because bed bugs hide deep in cracks and have developed resistance, while their eggs survive most pesticides.
Do not squish a bed bug as it will release the blood and any pathogens it may be carrying. Resist the urge to scratch the bites. your agency's policy in regards to whether a doctor's order is required.)
The two strongest attractants are heat and carbon dioxide, which mimic the warmth and breath of a sleeping human. They also respond to chemical signals, including pheromone trails, that help them follow paths to safe harborages or other bugs.
High heat (steam, hot dryer) and some contact sprays like rubbing alcohol or specific low-toxicity sprays kill bed bugs and their eggs instantly, but complete eradication requires persistent treatment like vacuuming, sealing cracks, using diatomaceous earth (DE), and washing items at high temperatures. While chemicals work, heat is highly effective, killing bugs in all life stages on contact, especially when temperatures reach 60°C (140°F) or higher, according to health.vic.gov.au and myhealth1st.com.au.
Bed bugs can sometimes survive washing machines if the water temperature is below 140°F, which isn't hot enough to kill all stages. Washing in cooler water or at standard temperatures may only knock out some bugs but leave eggs and others alive.
Many people cannot feel bed bugs crawling due to their quiet, swift movement and small size. Skin sensitivity varies; some individuals might notice a slight tickling or itching, while others may feel nothing. Bed bugs are nocturnal, often hiding during the day, making detection by crawling sensation less likely.
Bed bugs dislike strong scents like lavender, peppermint, tea tree oil, and eucalyptus. These natural aromas can deter bed bugs by creating an environment they find unpleasant, though they're not guaranteed to eliminate an infestation. Using essential oil sprays or sachets can help as a preventive measure.
Yes, Bed Bugs Can Live in Electronics
While electronics aren't a primary nesting site, they can absolutely be used by bed bugs as harborage — especially in moderate to severe infestations. Devices that remain close to sleeping or resting areas and emit gentle heat are particularly attractive.
Don't move things from room to room. Moving things from the room with bed bugs to another room in the house may spread the bed bugs. Don't wrap items in black plastic and place in the sun. It will not get hot enough inside the bag to kill all the bugs.
How do we know when the bed bugs are completely gone? ⇒ In case that you react to the bites, 3 weeks with no bites after the initial 2 weeks period waiting time after the treatment is a very good indication that the bed bugs are completely exterminated.
Showering can help remove any bed bugs present on your skin temporarily, as water and soap can disrupt their ability to cling to surfaces. However, showering alone is not sufficient to eliminate a bed bug infestation, as these pests primarily reside in hidden cracks and crevices within your home.
Contrary to popular belief, bed bugs do not actually live in hair—though they may bite at your scalp. They prefer to live in dark, secluded spaces, such as behind your bed, between furniture and walls, or within cracks on your floorboard.

Early signs of bed bugs include itchy bites in lines or clusters, rusty or dark spots on bedding (fecal stains), tiny pale eggs or shed skins in mattress seams, and a sweet, musty odor; you need to inspect mattress seams, bed frames, and furniture for these physical clues, as bites alone aren't always definitive.
If the room is heavily infested, you may find bed bugs:
Inspect Pillow Seams and Crevices
Bed bugs love to reside in tight, dark spaces. This makes pillowcase seams and crevices inviting hideouts.
The good news is that bed bugs cannot tell time, and they do not know much about your sleeping habits. They just wait for night to fall to make their appearances. What bed bugs want is for you to stop moving around. When you go to sleep, your body relaxes and stays still, making a perfect buffet for bed bugs.
Bed Bugs: A Public Health Issue
Bed bugs can reproduce rapidly. Females will lay one to five eggs per day, and one female can lay between 200-300 eggs over her lifetime. The eggs are white, about 1/32-inch long, and are covered with sticky glue that keeps them attached to the surface where they are laid.
Households had their own methods of controlling bedbugs. Wicker traps were in common use. They were placed behind the headboard and tempted bedbugs with what seemed to be a perfect hiding place. Each morning, the trap would be emptied into boiling water, killing adult bedbugs and nymphs.
